They are way ahead of the game. At first I figured they were the best choice for a 300-400whp car.... After tuning Manitou's XTi and seeing that even on a bigger turbo they work AWESOME I am sold. They spool faster, and make more power then the rest.

The rest of those brands are pretty much the same basic design that has been around for years

I swear it makes my Dom 3.5xtr spool like a VF. The response is just amazing and I feel like we'll get every bit of power out of that turbo. I really think they change the VE of our motors more so than almost anything else we can do.
